We create a float array color buffer.
我们创建一个浮点型数组颜色缓冲器。
Additional capabilities provide the means of testing the pixel color of a screen coordinate or even capturing a whole area of the screen as an image buffer.
其它的功能还提供了测试一个屏幕坐标的像素颜色的方法，甚至可以将屏幕上的一整块区域作为一个图像缓冲捕捉下来。
This pre-conversion is critical for maintaining color state through transitions of different frames as their portions are blitted to the buffer and, eventually, the screen.
帧的局部经过位块传输后保存在缓冲区，最终在屏幕显示。 这种预转换通过帧间转换，对保持色彩状态十分重要。
The depth buffer has the same width and height as the screen but holds z coordinates instead of color values.
深度缓冲与屏幕有着相同的宽和高，但用z坐标取代颜色值。
Finally, purify_what_colors is called to print the color of the memory buffer.
最后，purify _ what _ colors被调用来打印这个内存缓冲的颜色。
It then fills the area with a mapping, which is an image buffer used to color up the painting area of each stroke.
然后，它使用一个映射填充该区域，这个映射是用于对每个笔触的绘图区域着色的图像缓冲区。
This mode does not clear either the color or the depth buffer.
该模式不清除任何颜色或深度缓存。
The value of this stage is multiplied by frame buffer source color value.
此阶段的值是和源帧缓冲中源颜色的值相乘。
The value of this stage is multiplied by frame buffer source color value.
